The Road to Pearl Harbor: U.S.-Japanese Relations Between the Wars
Wednesday, May 20, 2026, 1:00 pm – 2:00 pm ET

On December 7, 1941, the Japanese Imperial Navy launched a surprise air attack on U.S. forces at Pearl Harbor, HI, drawing the United States into World War II. The roots of the Pearl Harbor attack reach back to Japan’s Meiji Restoration (1868–1912), which marked the rise of the Empire of Japan as a growing world power. After World War I, shifting political and economic conditions strained relations between Japan and the United States. Over time, the two nations’ friendship eroded, gradually giving way to the tensions that led to war. Please join Park Ranger Paul O’Brian to explore the key causes and events that shaped U.S.–Japanese relations and ultimately led to the attack on Pearl Harbor.

Please note: This program is only being offered as a simultaneous online webinar. Please contact the Library to obtain webinar information for this program.

The list combines the full-text journals and other materials in all the database services to which Library users have access.

Also included are some single subscriptions as well as selected open access books and journals. Most entries include coverage dates, and all entries have links directly to the requested title.
